Taiko’s bridge was exploited for up to $1.7 million after attackers forged cross-chain message proofs and drained its ERC20 vault.

Taiko's ERC20 vault was exploited for $1.7M due to a cross-chain bridge proof verification flaw, with $2M in TKO tokens deposited to MEXC by the attacker.

Onchain security firm Blockaid said the root cause of the exploit could be a flaw in Taiko bridge's source-signal proof validation.
